FRN-YT551T1-Ni2 is a kind of titania type CO2 gas-shielded flux-cored welding wire. It has excellent welding performance, soft and stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. All-position welding. It has high welding efficiency. The weld metal has been given toughening treatment by microelements, so it has excellent low temperature toughness above -30℃ and good crack-resistance.

Used for welding structures made of 590MPa low-alloy high strength steel. Widely used for welding some key structures like hoisting machinery, bridges, storage tanks, steel-frame structures, etc.
